== Version history ==
Version 1.1, introduced in June 1986, added support for the [[IBM PC Network]] and [[IBM 3270]] [[terminal emulation]]. Importantly, support for swapping non-[[Terminate-and-stay-resident program|resident]] programs was added&mdash;onto the hard disk on all computers and into the [[high memory area]] on machines equipped with a 286 CPU. The initially poor support for DOS batch files was improved.<ref name="IBM_1986_Announcement">{{cite web |publisher=IBM |type=Announcement letter |date=1986-06-25 |title=TopView Version 1.1 |url=https://www.ibm.com/docs/en/announcements/archive/ENUSZP86-4028}}</ref><!--This seems to indicate 1.11 may have been skipped over for TopView, because the PC LAN software needed a bug-fix release and the two programs had their version numbers synchronized{{cite |work=[[InfoWorld]] |date=1986-06-23 |author-first1=Karen |author-last1=Sorensen |author-first2=Laurie |author-last2=Flynn |title=IBM's Revision of PC LAN Released Without Fanfare |url=https://books.google.com/books?id=TC8EAAAAMBAJ&pg=PA5}} -->
